大庆油田是我国第一大油田,总占地面积约为六千平方公里,其主要勘探范围是东北和西北两大区域。这两大区域中的深部底层钻井在当前已掌握的技术下面临的问题主要存在于地温梯度较高、以及压力系数较低这两方面。大庆油田方面的科研人员根据自身油田所处地形,综合各方面问题进行了深入研究,最终研制出了抗200℃水包油钻井液、抗200℃有机硅钻井液及抗180℃泡沫钻井液,并且成功将这一部分研究成果应用到了实际工作中去,并且取得了一定的成效。
Daqing Oilfield is the largest oilfield in China with a total area of about 6,000 square kilometers and its main exploration area is the northeast and northwest two major regions. Deep underground drilling in both regions mainly faces the following problems in the current mastered technologies: high geothermal gradient and low pressure coefficient. Based on the topography of their own oilfields, Daqing Oilfield researchers conducted in-depth research on various aspects and comprehensively developed the anti-200 ℃ oil-in-water drilling fluid, the anti-200 ℃ silicone drilling fluid and the anti-180 ℃ foam drilling fluid, And successfully applied this part of the research results to the actual work, and achieved some results.
